On June 18, the major banking regulators in the United States plan to reduce key capital buffer requirements for large banks by up to 1.5 percentage points. Previously, there were industry concerns that the existing rules restricted banks' trading activities in the $29 trillion Treasury market. According to informed sources, the Federal Reserve, the Federal Deposit Insurance Corporation, and the Office of the Comptroller of the Currency are focusing on the so-called Enhanced Supplementary Leverage Ratio (eSLR), which applies to systemically important banks in the U.S. such as JPMorgan Chase, Goldman Sachs, and Morgan Stanley. The new proposal aims to lower the capital requirements for bank holding companies under the eSLR from the current 5% to a range of 3.5% to 4.5%. The capital requirements for bank subsidiaries are also expected to be adjusted down from 6% to the same range. This adjustment is similar to the 'customization' revision approach to the eSLR calculation for systemically important banks during the Trump administration in 2018, but the specific terms may still be modified.
